Peristaltic Pump
Installing the Drain Tubing
Install the drain tubing on an open channel of the peristaltic pump as follows:
1. Pre-stretch a piece of 1.14 mm (0.045 in.) pump drain tubing.
2. Carefully stretch the new tubing around the pump head and place the clips on
the pump tubing into the slots, using the slots in the same position on each side
of the pump head. Be careful not to twist or kink the pump tubing during this
process.
3. Attach the Teflon tubing to the pump tubing for the drain.
Make sure you install the tubing on the pump so that the waste liquid is
pumped out of the spray chamber. See Figure 5-40. If the tubing is installed
in the wrong direction, the spray chamber will flood.
4. For the tubing that leads to the drain bottle, use one piece of 1.07 mm i.d.
(0.042 in.) Teflon tubing (Part No. 09985708). Bevel one end by cutting it at
an angle.
5. Insert the Teflon tubing into the other side of the pump tubing. Lead this tubing
to the drain bottle. Refer to Figure 5-40.
6. Adjust the tubing as described in the next procedure.
